Laxometer

A laxometer is a measuring device for scalp skin mobility (or more specifically, laxity)[1] used in hair restoration surgery, where a strip of skin from a donor area on the back of the scalp is transplanted.

The laxometer was first presented at the 15th Annual Meeting of the International Society of Hair Restoration Surgery in Las Vegas.

and introduced as the first tool that could objectively measure the laxity of scalp in hair transplant patients.

[1] One issue with laxometers at the time is that they were not always accurate to measuring ideal properties as the measurement is influenced by a combination of subcutaneous fat, as well as the thickness and stiffness of skin.

This is relevant for those patients who have a high demand for hair and scarce resources.
